.SH DESCRIPTION
\*(CbSbSphereProjector\f1 is an abstract base class for projectors that use a sphere in their projection. Sphere projectors are typically used to write interactive 3D manipulators and viewers.

\f1Apply the projector using the given point, returning the point in three dimensions that it projects to. This also returns in \*(Cbrot\f1 a rotation on the surface of the sphere from the last projected point to this
\&one. The passed \*(Cbpoint\f1 should be normalized (i.e. lie in the range [0.0,1.0]), with (0,0) at the lower-left.
